Scalp Dermatologist in Las Vegas, Dr. Kendall Egan MD | Las Vegas Integrative Dermatology

When patients think about hair loss, they often focus on the hair itself — but healthy hair starts with a healthy scalp. Chronic scalp inflammation, itching, flaking, or irritation can disrupt the hair growth cycle and worsen shedding and thinning over time.

At Las Vegas Integrative Dermatology, we treat scalp health as a medical priority. As a board-certified dermatologist, I evaluate and treat scalp conditions that interfere with hair growth using an evidence-based and integrative approach.

Why Scalp Health Matters for Hair Growth

Hair follicles are embedded in the scalp skin. When the scalp is inflamed or unhealthy, follicles cannot function optimally.

Scalp inflammation can:

Shorten the hair growth (anagen) phase
Push hairs prematurely into shedding (telogen)
Weaken follicles over time
Reduce the effectiveness of hair loss treatments

Treating the scalp is often a critical — and overlooked — step in hair restoration.

Common Scalp Conditions That Affect Hair Growth

Seborrheic Dermatitis (Dandruff)

Chronic flaking, redness, or itchiness
Often worsens with stress or weather changes
Can increase shedding if untreated

Scalp Psoriasis

Thick scale and inflammation
Can disrupt hair growth during flares
Hair usually regrows once inflammation is controlled

Chronic Scalp Inflammation & Folliculitis

Burning, tenderness, or scalp pain
Inflamed follicles may shed hair prematurely

Contact Dermatitis from Hair Products

Irritation from fragrances, dyes, or styling products
Can cause itching, redness, and shedding

Scalp Conditions vs Hair Loss Disorders

Scalp disease can worsen underlying hair loss conditions and may occur alongside them.

Scalp inflammation + Female Pattern Hair Loss
Scalp disease + Telogen Effluvium (Stress Hair Loss)

If scalp disease is not treated, hair regrowth efforts are often less effective.

How a Dermatologist Evaluates Scalp Health

A medical scalp evaluation may include:

✔ Detailed scalp examination

✔ Assessment for redness, scale, follicle inflammation

✔ Review of hair products and treatments

✔ Evaluation for underlying hair loss patterns

✔ Treatment response monitoring

This is not something a salon or med spa can properly diagnose.

Treating Scalp Conditions to Support Hair Growth

Treatment depends on the diagnosis and may include:

Prescription medicated shampoos or topicals
Anti-inflammatory scalp treatments
Product elimination for contact dermatitis
Gentle scalp care routines
Microneedling (only when inflammation is controlled)

A calm, healthy scalp improves the success of all hair regrowth therapies.
